This article describes the plans which have been developed for the Census of Canada to be taken June 1, 1971. One of the most important features of this census will be the use of the Self-enumeration technique for the great majority of respondents. Other topics touched upon include the User Liaison Programme which established requirements, the Testing Programme which determined the methodology and some highlights of the Data Collection and Processing Phases of the operation. There is a brief discussion of the use of sampling in 1971 with particular emphasis on the benefits to be derived in increased quality and reliability of data, increased timeliness and reduction in respondent burden. The Quality Control procedures are described. The Post-censal Evaluation and Data Dissemination programmes are also dealt with.
